diluted to 500mL. A 50.00mL aliquot of this solution was treated with 40.00mL of 0.05304MHCl (phenolphthalein is indicator). An excess of neutral BaCl2 was added to another 50.00mL aliquot to precipitate the carbonate as BaCO3. The solution was then titrated with 28.56mL of the acid to a phenolphthalein end point. Calculate the percentage of KOH2K2CO3, and H2O in the sample, assuming that these are the only compounds present. (Answer: 69.66%KOH, 21.07%K2CO3, and 9.27%H2O ) 16) A 1.217g sample of commercial KOH contaminated by K2CO3 was dissolved in water and the resulting solution was diluted to 500mL. A 50.00mL aliquot of this solution was treated with 40.00mL of 0.05304MHCl (phenolphthalein is indicator). An excess of neutral BaCl2 was added to another 50.00mL aliquot to precipitate the carbonate as BaCO . The solution was then titrated with 28.56mL of the acid to a phenolphthalein end point. Calculate the percentage of KOH,K2CO3, and H2O in the sample, assuming that these are the only compounds present. (Answer: 69.66%KOH, 21.07%K2CO3, and 9.27%H2O )
